I bought a full set of kitchen appliances (built-in fridge/freezer, built-in dishwasher, ceramic hob, built-in oven and hood) from a PC in Lucan (well, the one between Lucan and Clondalkin) about two months ago. I got quotes for the same lot from Harvey Norman and DID and PC were best priced even before discount.
I just went in, had a look around, explained to the salesman what i was looking for and he knocked down several hundred Euro off the total. I have to say that I was very happy with the service, prices and the appliances I bought.
